OK here's an update. Originally had my car booked in at VW Ringwood to address incorrect coding on towbar. When trailer is connected & car is in reverse gear the rear sensors go into panic mode!! Apparently the RNS510 should be showing a pitcure of a trailer on the screen & disengage the rear sensors. Anyway, first time I dropped it off (for 2 days) they had fixed that problem but stuffed up the function of the RVC. Second time I dropped it off, RVC fixed, still need to attach trailer to see if original problem fixed but now the animiated view of the car on the RNS510 won't appear when I forward park. The front sensors still beep but I just don't know which ones. Oh BTW, my lane assist is now not working either. Need to now book a third trip in to VW Ringwood.

One of the other things I asked them to look at was the DSG issue I mentioned at the start of this thread. Apparently it is functioning "normally". I might have to take a B7 V6 for a test drive to compare.
